A warning that if you do an apt-get upgrade (upgrading all packages, including system packages) on a PiAware 3.3.0 or older sdcard image it is likely to break.
The simplest option to avoid this is to re-image with a PiAware 3.5.0 image.
If you can’t do that, avoid upgrading the system packages (upgrading just PiAware via the remote command or by “apt-get install piaware” is OK)
There are several interrelated problems, related to a new Raspbian kernel packge that was recently released:
- You will run out of space on /boot as the partition is not large enough to hold all the required kernels / initrd images / etc, which leaves the kernel half upgraded
- Using an old (4.4) kernel with newer Pi bootloader/firmware will produce a randomized MAC address on each boot due to an incompatibility with the older kernel
- The new kernel can panic on boot due to a kernel bug that is tickled by the config.txt (enable_uart=1 setting) used by the 3.3.0 image
Recovering this by hand is somewhat tricky so I strongly recommend you just go with a new 3.5.0 image.
